Register your wired device on the IU network

Overview

Before any wired (Ethernet-connected) device can establish an internet connection via the network at Indiana University, its network adapter(s) must be registered with IU's DHCP service. On campus, you can make a limited connection to IU's network to visit the DHCP registration page and register your device. After doing so, you'll have full internet access. For more information specific to Bloomington residences, see Ethernet cables for Bloomington residences.

If you need help, have a question, or want to report a problem, contact your campus Support Center, or the local UITS support person for your department or school.

Ethernet cables for Bloomington residences

The Ethernet cables required for Bloomington residence halls and campus apartments depend on the location. Some use standard commercial Ethernet cables, while others require special IU-proprietary Ethernet cables. If your room does not have an IU wall cable, you may obtain one from the TCC desk (fourth floor of the Wells Library West Tower). TCC does not provide standard, commercially available Ethernet cables. If you need a standard Ethernet cable, you will need to obtain one yourself.

Use the DHCP registration page

Students, faculty, and staff can register personally owned computers running Windows or macOS, most Linux computers, gaming devices with a built-in browser, and other supported Ethernet-enabled devices via IU's DHCP registration page.

To do so, you must first connect the computer or device (using an Ethernet cable or wireless) to the IU network.

Once your device is connected to the IU network:

1. Open a web browser. Your browser should be redirected automatically to IU's DHCP registration page; if it isn't, follow the steps for manual registration by a consultant.
2. Log in with your IU username and passphrase.
3. Follow the instructions on the registration page to enter your MAC address information and create the new device registration.

The DHCP service can take up to five minutes to process your registration. You should wait at least that long, and then restart your computer or device.

Manual registration by a consultant

UITS must manually register certain computers and networked devices, such as:

• Internet-capable televisions
• Gaming devices without a built-in browser

Consultants can also manually register your device if you are unable to complete the online process via the DHCP registration page.

Contact the Support Center to request manual registration, providing:

• Your building and room number (for Ethernet connections)
• Your IU username
• The type of device you're registering (for example, Linux workstation, iPad, Kindle Fire, Amazon Fire phone, or Wii U)
• The device's wired (Ethernet) MAC address

  To find the wired (Ethernet) MAC address, check the appropriate instructions below, or search the web, consult the manufacturer's technical support, or check with your cellular provider:

  • Find your Windows network adapter's MAC address
  • Find your macOS Ethernet or wireless interface's MAC address
  • Find your Android phone or tablet's MAC address
  • Find your e-reader's MAC address
  • Find your smart TV, DVR, or set-top box's MAC address
  • Register your gaming console or media device at IU

Re-register your computer or networked device

In some cases, you may need to re-register your computer or networked device; for example:

• To ensure the security and integrity of the IU network, UITS periodically purges old or unused network registrations. UITS also purges network registrations in the halls of residence on a rolling basis each fall semester.
• The University Information Policy Office (UIPO) and the University Information Security Office (UISO) can disable any IU user's access to the IU network for security reasons or policy violations. In such cases, UIPO will notify affected users via email.

If your device's network registration has been purged, the device will not be able to establish an Ethernet connection until you re-register it with the IU DHCP service (using IU's DHCP registration page).

For compromised or vulnerable devices, additional action is required; see If your network access has been disabled by UISO.

Number of networked devices you can register

If you are a campus housing resident, you may register up to five network-enabled devices in your residence.

If you live off campus and are not registering devices for use in campus housing, you may register up to 10 devices.

If you need to exceed the maximum number of registered devices permitted, contact your campus Support Center. If you are a faculty or staff member connecting a device within your school or department, contact the local UITS support person who supports your area.
